Using trace I see that I have multiple cookies with the same name? This is causing problems because I am loggin into many different accounts on the same site I am developing and values are getting confused.
I always thought that setting a cookie value overwrote a previous cookies value not created a duplicate, this is using IE 7 if that makes a difference.
Here is a list of cookies for example, note the duplicate ShipState, EmailAddress, CustomerID:
EmailAddress firstname.lastname@example.org 34
